ABSTRACT:
An improved liner and method is taught for use in protecting a wearer's skin from moisture retention when worn with prosthetic devices and other substantially non-breathable shells. The liner is form fitted to attach to a wearer without bunching or other pressure points which can cause skin irritation. Preferably, the liner comprises a membrane of expanded polytetrafluoroethylene coated on its interior surface with a polyurethane material to aid in moisture isolation and to protect the liner from compromise due to oils and other contaminants found in perspiration. The liner is effective at shielding a wearer's skin from moisture even when worn with no separate absorbent layer.
